Abstract: In this paper, we propose a proximity based automated access control (PBAC) model for smart-ED environments which improves the existing ED work-flow by automating mundane administrative procedure for secure information access, allowing caregivers to focus on the treatment of patients. The proposed access model builds on the traditional role-based access control model and extends it by including multiple authentication levels for preventing unauthorized access. We also provide a semi-formal specification for the PBAC model. We further validate it using ultra-wide-band (UWB) based prototype which was tested in ED.
